Answer:
4 hours
Step-by-step explanation:
The general formula for distance, rate and time is:
d = rt, where distance is the product of rate multiplied by time
Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles. Using the variable 't' for time:
70t + 62t = 528
Combine like terms: 132t = 528
Divide both sides by 132: 132t/132 = 528/132 or t = 4 hours

C. <span>(-0.5, -4.25)
is your answer
(-b)/2a
(-1)/2(1)
x = -1/2 = -0.5
</span><span>y=x^2+x-4
y = (-0.5)^2 + (-0.5) - 4
y = -1 - 0.5 - 4
y = -4.25</span>
